Method and apparatus for determining recording pulse parameters for an optical disc

Abstract

If data is recorded using a disc with deviating characteristics and a recorder with deviating characteristics, data will not be appropriately recorded, and errors will occur in the read signal. Standard recording pulse parameters specifying recording pulse positions for plural possible mark length and space length combinations are read from a writable optical disc, these standard recording pulse parameters are then used for test writing, the standard recording pulse parameters are changed uniformly or individually, a best recording pulse parameter is thus obtained, and jitter can be reduced.

Description

[0001] This is a divisional application of Ser. No. 09 / 582,675, filed Jun. 29, 2000, now U.S. Pat. No. 6,791,926 which corresponds to International Application PCT / JP99 / 06158, filed Nov. 5, 1999.TECHNICAL FIELD

[0002] The present invention relates to a method and apparatus for determining the recording pulse parameters of an optical disc by reading standard recording pulse parameters from a writable optical disc, the optical disc having standard recording pulse parameters prerecorded to a specific area thereof, setting the recording pulse parameters of a recording and reproducing device, and recording or reproducing data from the disc.BACKGROUND ART

[0003] The DVD-RAM specification describes one example of a high data capacity rewritable optical disc, and devices capable of writing 2.6 gigabytes of data using a mark edge recording method to one side of a 12 cm diameter disc using a phase change recording film are available. Looking to achieve an even higher density optical disc medium, t...
